openclaw - 💡(How to fix) Fix Bug: pi-ai Anthropic provider crashes on malformed responses (anthropic.js:590) [1 participants]

TL;DR

Adding a null check for b.text before calling trim() on it is likely to fix the crash in the Anthropic provider.

Guidance

• The crash occurs because b.text is not checked for existence before calling trim() on it, similar to how it's properly handled in openai-completions.js.
• To verify the fix, test the Anthropic provider with malformed responses that cause b.text to be null or undefined.
• The code change should be applied to pi-ai/dist/providers/anthropic.js at line 590, adding a null check similar to (b.text && b.text.trim()).
• Consider adding additional error handling or logging to handle cases where b.text is null or undefined.

Example

// Before
const trimmedText = b.text.trim();

// After
const trimmedText = b.text && b.text.trim();

Notes

This fix assumes that the intention is to skip trimming if b.text is null or undefined. If b.text is expected to always be present, additional error handling may be necessary.

Recommendation

Apply the workaround by adding a null check for b.text before calling trim(), as this directly addresses the identified issue and prevents the crash.
